Teleseismic Radial Anisotropy Reveals a Sill‐Dominated Magma Reservoir Beneath the Valles Caldera, New Mexico

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Valles Caldera (VC), one of the largest Quaternary silicic calderas in North America, formed by explosive rhyolitic eruptions. Seismic studies suggest a crustal magmatic reservoir beneath the caldera with low‐velocity anomalies, but resolving the detailed geometry of localized melt requires constraints from seismic anisotropy.

Holistic Retrieval of Absolute Coseismic Displacement Fields From Single Interferograms via Physics‐Aware GANs

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Quantifying and Classifying Non‐Stationary Turbulence Under Sub‐Mesoscale Disturbances

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Non‐stationary turbulence induced by sub‐mesoscale disturbances can substantially bias flux estimates, yet is largely overlooked in existing evaluation frameworks. Using turbulence measurements over the heterogeneous Loess Plateau, we found that classical stationarity tests classify >60% of records containing clear submesoscale disturbances as

Topographic Anchoring and the “Silent Period” of Deep‐Water Polynyas in the 90°W–90°E Antarctic Sector

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Antarctic deep‐water polynyas act as critical windows driving deep ocean ventilation, exerting profound impacts on the global thermohaline circulation and biogeochemical cycles. Utilizing high‐resolution satellite remote sensing and ocean reanalysis data from 2003 to 2022, this study identified eight recurring deep‐water polynyas within the ...

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Collapses of Hemispheric Available Potential Energy

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The atmospheric circulation in the midlatitudes is maintained against dissipation by converting available potential energy (APE) into kinetic energy (KE). During boreal winter this energy reservoir occasionally collapses, releasing up to 10% of hemispheric APE within days.
